LANTERN.,

SPECIFICATION forming part of Letters Patent No. 382,831, dated May 1,5, 1888.

Application inea May 31, 1881. serial Norme-1. (ne maar.) i

To all whom it may concern: i

Be it known that I, FRANK RHIND, a citizen of the United States, residing at Meriden, county of New Haven and State of Connectieut, have invented an Improvement in Lanterns, of which the following'is a specification. I My invention-relates to that classv of lanterns which is adapted to receive a lamp requiring a chimney, and is intended to prevent the smoking of the chimney or. the extinguishing ofthe lame by the force ofthe wind. It is especially advantageous when applied to streetlamps,where a large steady flame is required. In the accompanying drawing,which represets in perspective a streetlantern. embodying my improvement, A designates a body or frame of a lantern provided with polygonal sheets of glass a and with plates of perforated metal a a" at itsupper and lower edges; a, a wind guard or metal wall attached to the bottom of the frame A; B, an inner frame orbody,

also provided with polygonal sheets of glass b; C, a roof or top,which vmay have a cowl, c; D, a lamp; D', a chimney in the lantern.

My invention is constructed and operated as follows: The body or frame A of the lantern is constructed of the ordinary material andin the usual shape, a solid metal bottom and a frame flanged or recessed to receive the glass sides a being the form shown.` Below the sheets of glass a strips of perforated metal c are rmly secured to the bottom and frame of the body A. Through these strips c" air is admitted to support the'llame and produce an upward curr'ent. Vertical walls or wind-guards a are attached to the bottom of the lantern frame or body A. They' are of substantially the same height as the perforated strips a, and serve to prevent eduction of air at the bottom of the lantern. In the drawing they are shown as extendingl radially from the lamp D to the corners of the frame A.r

Above the sheets of glass a other strips of perforated metal, c', are secured to the frame. Through these strips a air may pass into or out of the lantern, as will be more fullyV explained. The inner'frame or body, B, is preferably made integral with the roof ortop C, which is provided with a horizontal flange 5o tted to rest onthe frame A, and is flanged or recessed to receive the sheets of lglass b.

spaceA is left between the inner' sheets of glass, i

yb, and the outer sheets, c. Through this space must pass all the air that passes through the perforated 'strips a. The roof or top C may be made of glass or metal, as desired, and is provided with a cowl of any suitable construction. Whenthe lamp and lantern are in use in calm weather, a large supply of air enters through the perforations in the stripsu at the is used to support combustion. rIhe remainder, with the'products of combustion, passes upward and escapes partly through the cowl c, partly through the spaces between the sheets of glass b and the sheets a, thence'through the perforated strips a. When, however, a wind of considerable force is blowing, a downward current `of air i s sometimes created through the cowl c, which tends to create a similar downward current in the lampchimney D', thus causing imperfect combustion with'discoloration of the chimney, and'frequently'extinguishing the llame. To overcome this diffieulty is a main object of the present construction. When a downward current is created through the cowl c, a similar downward` rcurthrough the'strips c in creating a pressure of air at the bottom of the lantern and to neutralize the downward current through the cowl c. In practice a lantern o f this constructionv is found to withstand a strong windwithout seriously altering the shape or size of the dame. l

I have drawn and described a street-lantern of ordinary square pattern; but it is obvious that the invention is equallyv applicable to street-lamps of cylindrical or globular form, it only being essential to my invention that double translucent walls be employed,with an air- 6o bottom ofthe lantern. A portion of this` air space between them, and that the inner wall shall extend downward to apoint between the top ofthe lamp-chimneyand the bottom of the lantern. It is equally obvious that my invention is applicable to hand-lanterns of various shapes, to ship or reiiector lanterns, and to nearly all forms of inclosed lamps for outdoor use.

The particular advantage of my invention, in addition to that above named, is that by means ofthe upward or downward current of air passing between the walls a and b the outer wall, a, is kept at so low a temperatu re as not to be liable to breakage from the contact with its exterior surface of rain or snow. Hence a street-lantern of ordinary size constructed as above described may be used with a lamp giv ing a much larger iame than has heretofore been customary, and is particularly adapted for a large Argand or center-draft lamp.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is as follows:

l. In a lantern, the combination of a chimney-bearing lamp, a translucent chimney acting in conjunction with said lamp, an outer translucent lantern-wall, an opening for the admission or emission of air at the upper edge of said outer wall, and an inner translucent lantern-wall separated from the outer wall by an air-space and extending downward to a point below the top ofthe lamp-chimney and above the lower edge of the outer wall, substantially as described.

2. In a lantern, the combination of a chimney-bearing lamp, a translucent chimney aeting in conjunction with said lamp, an outer translucent lantern-wall, an opening for the admission or emission of air at the upper edge hof said outer wall, an inner translucent lantern-wall separated from the outer wall by an air-space, and a lantern roof or top from which said inner wall depends, substantially as described.

3. In a lantern, the combination of a chim` neybearing lamp, a translucent chimney acting in conjunction with said lamp, an outer translucent lantern-wall, an opening for the admission or emission of air at the upper edge of said outer wall, an inner translucent 1antcrn-wall separated from the outer wall by an air-space, and alantern roof or top from which inner wall depends, said roof being formed with a covered or protected opening, substantially as described.
